Then the snake darted at the mother-bird and swallowed it, when Zeus changed the reptile into a stone. The Greeks wondered at the sight, but the soothsayer, Calchas, said to them: "Why do ye wonder at this? The all-powerful Zeus has sent us this sign because our deeds shall live forever in the minds of men. Just as the snake has devoured the eight little sparrows and their mother, so shall the war swallow up the nine coming years, and in the tenth we shall overcome Troy."

The ships of the Greeks lay in the bays of Aulis while the warriors waited impatiently to set sail. But the winds were contrary; they would not blow, and the boats waited there year after year; for a sacred hind had been slain by Agamemnon, one that belonged to the goddess Artemis, and it was ordered by that goddess that no wind should arise to take them on toward Troy until her wrath had been appeased.

So Agamemnon went to Calchas, the seer, and asked his advice, whereupon the old prophet told him to send for his lovely young daughter, Iphigeneia, and offer her up on the altar as the only acceptable sacrifice to Artemis. When he had placed her upon the altar and the priest was raising his knife, the goddess took pity on Agamemnon and carried the girl away in a cloud, leaving a fine white doe instead.

ODYSSEUS AND MENELAOS PERSUADING AGAMEMNON TO SACRIFICE IPHIGENEIA

And now arose a favorable wind, and the Greeks arrived safely before Troy. How they fought with the Trojans, how many of the heroes outlived the struggle, and how many fell in the battle, all this we can learn from an old book called the "Iliad." We shall select from it only those things which refer to our hero, Odysseus; and to complete the history of that hero we shall go to another book, called the "Odyssey."

Both of these books are the work of the great poet Homer, who lived many years after the war with Troy. That we may understand better what happened later on, we must give a short account of the fall of Troy and of the return of Menelaos and Agamemnon to their own country.
